Controlled moisture removal in a laundry treating appliance
A method of operating a laundry treating appliance for treating laundry according to a treating cycle of operation. The laundry treating appliance comprises a treating chamber for receiving the laundry that is selectively accessible through a door movable between opened and closed positions. The method comprises determining at the end of a laundry treating cycle whether the door has been opened and subsequently reclosed and reducing humidity in the treating chamber after the determination that the door has been reclosed.
1. An automatic washing machine for treating laundry according to a treating cycle of operation, comprising:
a cabinet;
a user interface arranged on the cabinet for receiving instructions from a user of the washing machine;
a drum housed within the cabinet and configured to rotate about an axis and defining a treating chamber within the cabinet for receiving laundry to be treated;
a door for selectively providing access to the treating chamber;
a water inlet for supplying water to the treating chamber;
a fan located within the cabinet and configured to rotate to draw air from an exterior of the cabinet towards the treating chamber;
a sensor for determining the presence of laundry in the treating chamber; and
a controller configured to control a plurality of cycles of operation of the washing machine, including at least one treating wash cycle where the water inlet supplies water to the treating chamber and a humidity reduction cycle without the addition of water, the controller configured to, in the humidity reduction cycle and in response to the sensor indicating the presence of laundry in the treating chamber, rotate the drum and the fan to draw air into the treating chamber.
2. The washing machine of claim 1 , further comprising a vent arranged between the treating chamber and a front side of the cabinet to create an air flow path therebetween.
3. The washing machine of claim 2 , wherein the fan rotates to provide air flow through the vent.
4. The washing machine of claim 2 , further comprising a second vent arranged between the treating chamber and a back side of the cabinet to create a second air flow path therebetween.
5. The washing machine of claim 4 , wherein the fan rotates to provide air flow through the second vent.
6. The washing machine of claim 1 , wherein the sensor is a weight sensor.
7. The washing machine of claim 1 , wherein the sensor is a door sensor configured to detect one of an open and closed door positions.
8. The machine of claim 7 , wherein the controller is further configured to determine whether the door was opened and subsequently closed within a predefined amount of time based on the door position from the door sensor.
9. The machine of claim 7 , wherein the controller is further configured to execute the humidity reduction cycle in response to the door being closed within a predefined amount of time following the door opening after the completion of the treating cycle of operation.
10. The washing machine of claim 1 , wherein the controller is configured to instruct the drum to rotate during the humidity reduction cycle in one of clockwise or counterclockwise direction.
11. The washing machine of claim 10 , wherein the controller is configured to instruct the drum to alternate rotation during the humidity reduction cycle between the clockwise or counterclockwise directions.
12. An automatic washing machine for treating laundry according to a treating cycle of operation, comprising:
a cabinet;
a treating chamber defined within the cabinet for receiving laundry to be treated;
a door for selectively providing access to the treating chamber;
a fan located within the cabinet and configured to rotate to draw air from an exterior of the cabinet towards the treating chamber;
a sensor for determining the presence of laundry in the treating chamber; and
a controller configured to control a plurality of cycles of operation of the washing machine, including at least one treating wash cycle where a water inlet supplies water to the treating chamber and a fluff cycle without the addition of water, the controller configured to, in the fluff cycle and in response to the sensor indicating the presence of laundry in the treating chamber, rotate the drum and the fan to draw air into the treating chamber.
